Question
Data Interpretation and Analysis Exercise 9.135: Lattice Energies of Period 4 Elements Evidence for the additional stabilization of certain electron configurations comes from the experimental lattice energies of the metal fluorides - MF_2. Figure 1 (Figure 1) plots lattice energy for the 2 + metal cations for period 4 elements. Figure 2 (Figure 2) plots the ionic radii of the 2 + metal cations for period 4 elements versus atomic number. Use the information provided in the figures to answer the following questions. Which has the higher lattice energy: VF_2 or VC1_2? Indicate your answer along with the corresponding reason by classifying each claim below. Drag the appropriate items to their respective bins.Explanation / Answer
Which has the higher lattice energy VF2or Vcl2
VF2
2812-----------------answer
Vcl2
2550
VF2
Contains the smaller anion
Smaller distance between V2 and the anion
Higher lattice energy
==============================
Vcl2
Contains the larger anion
Lower lattice energy
Longer distance between V2 and the anion
=====================================================
lattice energy increases ------------------ the cation-anion distance decreases.
Vanadium(II) chloride is the inorganic compound with the equation VCl2, and is the most lessened vanadium chloride. Vanadium(II) chloride is an apple-green strong that breaks down in water to give purple arrangements.
Strong VCl2 receives the cadmium iodide structure, including octahedral coordination geometry. VBr2 and VI2 are fundamentally and artificially like the dichloride. All have the d3 design, with a quartet ground state, likened to Cr(III).
Vanadium dichloride is an intense lessening animal groups, having the capacity to change over sulfoxides to sulfides, natural azides to amines, and additionally reductively coupling some alkyl halides.
